Title: Improvements in the manufacture of composite articles
IPC: B44C1/14
Filed: 1934-02-09
Abstract: 433,138. Compound fabrics &c. BRITISH CELANESE, Ltd., and MOSS, W. H., 22, Hanover Square, London. Feb. 9, 1934, No. 4321. [Class 140] Composite articles are produced by causing two components of different nature to adhere to opposite faces of a mixed fabric containing threads of different nature which are capable respectively of firm adhesion to the two components. Thus, a film or foil of cellulose acetate is united to a surface of wood, &c., by means of a fabric having a cellulose acetate weft and a cotton warp; the fabric being united to the foil by heat, with or without pressure, or by means of a solvent or adhesive and to the wood &c., by glue or casein. Cellulose derivatives other than cellulose acetate may be employed, the same derivative preferably being employed for the film, fabric and adhesive. Fabrics containing textile materials other than cotton, e.g. wool, silk or cellulosic artificial yarns, may be employed. The fabrics may be knitted, netted or woven. Decorative effects may be obtained by employing a dyed fabric with or without a mottled film. Suitable cellulose derivatives, solvents, softeners, &c. are specified. In an example, a film composed of cellulose acetate, monomethyl xylene sulphonamides and tricresyl phosphate is brushed, sprayed or otherwise coated with an adhesive composition comprising cellulose acetate, triacetin, acetone, benzole, alcohol and diacetone alcohol; after dyeing for a few minutes it is pressed on to the cellulose acetate face of a satin fabric woven with a cellulose acetate weft and a cotton warp, and allowed to dry. The cotton surface is secured to wood &c., by glue.

Title: Improvements in and relating to circuits for electric pulses
IPC: H03K3/543
Filed: 1946-07-31
Abstract: 652,408. Pulse generating circuits. GENERAL ELECTRIC CO., Ltd., and LEVY, M. M. July 31, 1946, No. 4341/50. Divided out of 652,353. [Class 40 (vi)] Two or more pulses, applied to a tuned circuit cause a damped wave to be generated, the pulse width and separation and the resonant frequency of the circuit being such that the shock excitation wave produced by the pulse or pulses after the first reduces the amplitude of a peak in one sense which occurs, after the first peak of the damped wave. The output pulse is obtained by clipping the resulting waveform. A pulse pair, Fig. 11 (a) applied to valve 10, Fig. 10, causes wave trains (b) and (c) due to the respective pulses to occur across the inductor L tuned by its stray capacity. The next waveform (d) occurring at the grid of cathode follower 39 shows a peak 25 with succeeding positive peaks substantially suppressed.

Title: Improvements in or relating to methods and apparatus for producing component parts for a radiator by welding
IPC: B21D53/08
Filed: 1963-02-05
Abstract: 1,037,541. Making radiators; welding by pressure; welding by fusion. RUNTAL HOLDING CO. A.G. Feb. 5, 1963 [Feb. 5, 1962], No. 4747/63. Headings B3A and B3R. In making a component part for a radiator, ribs are held on a tube transversely to the longitudinal axis of the tube and relative movement is effected between the ribs and a welding machine to weld the ribs to the tube. A radiator comprising three side by side flat tubes la, 1b, 1c, Fig. 1 (not shown), and upper and lower corrugated sheets 2a, 2b is assembled on a guideway 3, Fig. 5, and held together and jaws 5, one on each side of the guideway, move towards the radiator assembly so that fingers 5a and 5b on the jaws enter the corrugations in the sheets 2a, 2b to hold the assembly correctly positioned relatively to the electrodes 4a, 4b, Fig. 4 (not shown), of a welder 4 and faces 5c on the jaws press the tubes 1a 1b, 1c together. The guideway is moved transversely towards the electrodes which when the radiator is correctly positioned come together and effect spot welding of the bases of the corrugations to the tubes. The guideway is moved stepwise until all the transverse weld spots are made, the jaws 5 are withdrawn, the radiator is advanced on the guideway to bring another corrugation base in line with the electrodes, the jaws are returned and the guideway is moved transversely in the opposite direction. A baseplate 6 adjacent the welder 4 has guides 8, Fig. 9 (not shown), for guiding slides 7 carrying the jaws 5 and has two guideway parts 14, 15, each comprising a support surface 3a<SP>1</SP>, b<SP>1</SP> and fixed and movable side cheeks. Extension guideway parts 9, 10 are secured to the plate 6 and the assembly of plate 6 and parts 9, 10 is movable transversely in steps by rollers 19 on rails 18 by chain drives 26 driven by a shaft 25 in turn rotated by a pneumatic piston operated ratchet device. When the guideway reaches in end of its traverse travel a limit switch is operated which causes the jaws 5 to be withdrawn and the opening of the jaws causes the operation of a pneumatic cylinder 49 which via linkage 50 and a lever 51 moves the radiator assembly along the guideway one step. The electrodes may be moved relatively to the radiator assembly and seam welding instead of spot welding may be employed. Two flat tubes spaced apart may have ribbed metal sheets welded thereto and a flat tube may have individual flanged ribs welded thereto. Two electrodes may replace each electrode 4a, 4b or automatic arc welding may be used for welding individual ribs or hollow flat tubes to radiator elements.

Title: Improvements in spot suppression circuits in a cathode-ray tube

Filed: 1966-02-03
Abstract: 1,120,005. Cathode-ray tube circuits. COMPAGNIE FRANCAISE THOMSON HOUSTONHOTCHKISS BRANDT. 3 Feb., 1966 [3 Feb., 1965], No. 4871/66. Heading H4T. The beam of a cathode-ray tube is suppressed during fly-back periods by the application to the control grid W (Fig. 5) of negative pulses derived in a circuit including a transistor T supplied with signals occurring in the line and frame scanning circuits BL, BT during flyback periods. Such signals are not of the ideal shape (rectangular) for correct suppression tending rather to approach a semi-sine curve and to be accompanied, particularly in the case of signals from the line scanning circuit, by parasitic (overshoot) pulses, the former resulting in only partial suppression during the fly-back and the latter resulting in unwanted blanking during the commencement of the trace period (Fig. 3, not shown). These defects are removed by adjustment of the ratio of the potential divider formed by resistors R 1 , R<SP>1</SP> 1 , and R 2  to make the amplitude of the parasitic pulses slightly lower than the cut-off voltage of the transistor so that the latter passes rapidly from cut-off to saturation on the occurrence of the true fly-back signal resulting in the production of rectangular suppression pulses of the correct width and substantially free from the parasitic pulses.

Title: Microwave heating apparatus
IPC: H05B6/72
Filed: 1975-02-05
Abstract: 1501973 Microwave oven MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 5 Feb 1975 [8 Feb 1974] 4915/75 Heading H5H A microwave oven supplied with microwave energy distributed throughout the heating space has a microwave generator 3 coupled to a surface wave transmission line 14 which concentrates energy in the vicinity of its surface and thus allows the surface of foodstuff to be browned. The surface wave transmission line 14 may be formed as a metal plate 7 with high impedance elements, e.g. slots 8 arranged in a repeating pattern, as slots in a printed circuit pattern on an insulating board, as a metal plate with slots bounded by projecting metal teeth, as metal rods projecting transversely from metal plates like a U.H.F. antenna, as a slotted metal cylinder surrounding the item to be heated, or as a dielectric plate without any periodic pattern of high impedance elements. A dielectric plate, e.g. a plastics plate is preferably placed over the transmission line to cover the slots 5. The energy is coupled to the transmission line 14 by passage 6 beneath the line 14 into which the antenna 9 projects. By suitable dimensioning of passage 6 various energy modes can be supported and energy can be radiated throughout the chamber 4 in addition to that in the vicinity of transmission line 14. In Fig. 13 (not shown) the passage 6 is divided by conductive plates or bars between parallel rows of slots in transmission line 14 to improve the energy distribution. In Fig. 14, energy from the magnetron 3, 9 may be directed in adjustable amounts directly to the chamber 4 via a passage 4b or to the surface of the transmission line 14 via the passage 6. A metal baffle 16 pivoted in the passage 4 permits such adjustment. The adjustment baffle 16 may be dispensed with In Fig. 21 (not shown) the metal baffle 16 is replaced by an electric discharge tube in the passage 4b. When the discharge tube is energized from a separate supply it prevents energy passing directly to the chamber 4 via passage 4b. In Fig. 15 (not shown) the magnetron is mounted at the top of the oven and the passage 6 is defined between the top and side walls of the casing and an L-shaped partition plate, and between the transmission line 14 and the base of the casing. An aperture in the top of the partition plate enables energy to be introduced directly into the heating chamber. In Fig. 16 (not shown) the partition plate is omitted and the energy radiated into the chamber directly is coupled to the passage 6 below the surface wave transmission line 14. In Fig. 19 (not shown) a dielectric plate of glass, plastics or ceramic in contact with the lower surface of the transmission line 14 constitutes the passage 6.

Title: Colouring of textiles
Filed: 1957-02-14
Abstract: Textile material comprising both cellulose fibres and fibres of a heat-set cellulose triester, e.g. cellulose triacetate, are subjected to a mercerizing treatment to increase the affinity of the cellulose fibres for leuco vat dyes, then to the action of an alkaline leuco vat dyestuff and finally to an oxidizing treatment to re-form the insoluble parent vat dye, the cellulose fibres being coloured but the triester fibres remaining substantially undyed by the vat dye.  The triester fibres may subsequently be dyed, e.g. with disperse dyestuffs, or alternatively the triester fibres may be dyed prior to heat-setting.  The heat-setting operation may be effected on the mixture of cellulose and cellulose triester fibres or the triester fibres may be heat-set prior to mixing with the cellulose fibres. Mercerizing of the cellulose fibres is effected, e.g. with 20-25% aqueous caustic soda, preferably after a preliminary scouring treatment.  The vat dye may be applied in its reduced form or as a finely-divided aqueous dispersion and then reduced on the fibre.

Abstract: 1499063 Separator for pneumatic conveyor WAESCHLE MASCHINENFABRIK GmbH 10 Feb 1976 [13 Feb 1975] 05180/76 Heading BIT A gas-solids separator for the downstream end of a pneumatic conveyor comprises a housing enclosing upper and lower filter elements 3, 7 whose interiors are separated by wall 9, the upper element being connected to blower 6 and the lower element to passage 10. In Fig. 1 the blower 6 is unidirectional and a rotary valve 5 applies blower suction to element 3 to draw gas and solids in through inlet 12, past resilient flap valve 13, while applying some suction to passage 10 which holds resilient flap valve 11 closed. When sufficient solids have accumulated in hopper 18, valve 5 is rotated to apply the pressure side of blower 6 to the inside of element 3, which reverse-flow cleans element 3 with gas which then passes inwards through element 7 and out through passage 10, while solids discharge through weighted flap valve 20 (Fig. 2 not shown). On restoring valve 5 to the Fig. 1 position (Fig. 3 not shown), valve 11 which is biassed towards its open position remains open briefly so that some air is drawn in to reverse-flow clean element 7, then the suction closes valve 11. Valve 5 may be moved automatically by device 22 when the solids level reaches detector 23 and restored to the position shown in response to valve 20 closing after the solids have been discharged. Alternatively the detector 23 is omitted, and the opening of valve 20 by the weight of solids actuates device 22 to move valve 5. In Figs. 4-6 (not shown) valve 5 is omitted and blower (24) is reversible automatically by device 22 and level detector 23, operation is otherwise as above. A particular application is conveying plastics powder of below 50 microns dia. to a processing machine.
